Pressure Control Settings
Wiring Diagram
The temperature is controlled by an adjustable pressure
control located in the machine compartment. An
adjustable control has the word
COLDER
near the knob,
with an arrow to indicate the adjustment direction. These
controls are field adjustable and do not require a service
agent. If you have any questions, feel free to contact the
Delfield Service Department.
The refrigeration system on self-contained models was
adjusted at the factory to maintain between 36°F and
40°F. No adjustment should be necessary. If adjustment
does become needed, however, the factory recommended
settings are:
Operating pressure:
80 psi cut-in, 50 psi cut-out, 30 psi
differential.

If your Delfield unit has excessive condensation on the
refrigerated glass, the temperature should be adjusted to
maintain 41° to minimize condensation.
There is a hanging thermometer in the refrigerated section.
Please note that the adjustment needed is very small
and it will take the case 24 hours to equilibrate after the
adjustment is made.
